Safety
Short circuit
An unintended low-impedance electrical connection between conductors at different potentials.
Hazards
- An unintended low-impedance electrical connection between conductors at different potentials.
Controls
- De-energize and investigate damage, insulation, protection, fault current, and cause before re-energizing.
Personal protective equipment
- Select task-specific PPE only after hazards and higher-order controls have been evaluated.
Regional considerations
- Applicable law, permits, collective agreements, venue rules, and qualified-person decisions take precedence.
In practice
De-energize and investigate damage, insulation, protection, fault current, and cause before re-energizing.
